|Platform||Intel 64bit||OS||Ubuntu Studio||OS Version||14.04|
|Target Version||Fixed in Version|
|Summary||0007486: Assertins when cuting regions|
|Description||Sometimes Ardour crashes when cutting reagions with the cut tool. When using the split feature, no crashes occur.|
ardour-5.12.0: ../gtk2_ardour/editor_drag.cc:829: virtual void RegionMotionDrag::motion(GdkEvent*, bool): Assertion `!_views.empty ()' failed.
See attached backtrace for more information
|Steps To Reproduce||Not always reproducible. Trying to cut a region via click-drag to the exact point and then letting go of the mouse button. On my machine, aber about 5-10 cuts it crashes.|
|Additional Information||Backtrace of the assertion is attached. Ardour was compiled with optimization.|
|Tags||No tags attached.|

I cannot reproduce this issue with 5.12 using the cut tool/mode and splitting regions several hundred times in as many different ways as I can.
Is there any other information or steps that might be relevant in order to reproduce this?
The backtrace you have attached indicates that a region move is occurring at the time of the crash but AFAICT you cannot move a region in cut mode?
Ok, what might be relevant is that the region to be cut is in a track which is part of a group (think a guitar track and a guitar DI track which should be edited simultanously). The group was sometimes enabled, sometimes disabled when cutting, crashes occured on both occasions (with group enabled/disabled).
The split region function never showed the crash, only the cutting tool, so this was the workaround.
Also it crashed most often with the click-drag-release for finding the right place to cut (which I could imagine could be the source of the region move?)
I also observed this from Ardour 5.8 onwards as I do more often editing of the audio.
